Yes, thank God if you can be aware of the various possibilities that cannot always be avoided even though you feel that you have made the right decision when you bet, understanding and seeking information from various sides related to the two teams that will compete is a good dedication to increase the chances of winning, I also do the same thing but one thing I never forget is to keep limiting my expectations of victory in addition to limiting the amount of budget at stake, because what is feared is when my expectations are too high but it turns out that in the end the results are wrong or not in accordance with expectations then at least the annoyance will definitely be felt.
Limiting everything is indeed one of the things that must be considered, I even think it is the key for us to be in good condition, limiting expectations as you said is a small or trivial thing but when someone already expects more from the game or the benefits, it can actually be a weapon for them where they can fall deeper into their expectations. In addition, we must also be able to limit other things such as our own behavior by doing what we do.
Like limiting our own budget by looking at our own abilities, because there are players who do not see this, or they forget about this when they have made bets with disappointing results indirectly it can make them more interested. In addition, we must be able to see the risk side that is clearly certain to occur, we must be able to think about the risk itself, don't forget it, sometimes taking risks is something that must be done but considering it is also quite important.
Well that's the reason why I said that limiting the amount of budget to be wagered along with limiting our expectations or hopes for victory is quite important in gambling, namely to minimize various unwanted possibilities, because as you said where when they put too much expectation and it turns out the results are not as expected then of course what is feared is that emotions will dominate and in most cases this situation is what leads gamblers to various crazier actions.
On the other hand, one of the reasons why putting limits on some aspects is always recommended is because in any case we cannot get away from the fact that gambling will always be an activity that cannot be predicted about the results that will come out, which is added to the risk is always another possibility that will continue to lurk you every time you bet, so make sure that everything remains balanced, don't focus too much on winning, understand that if you are lucky then victory will also come to you you are being chased.
